Without knowing the specific product you inquiring about, I will say that many kelp fertilizers in liquid form and the water-soluble kelp powders are processed using potassium hydroxide. Despite this processing using an inorganic compound, many still claim "organic" status.
These products are incredibly effective at giving your plants a boost in potassium levels (and increasing yields) but run a real risk of throwing off your soil's microbiome.
Kelp Meal is much better for the overall health of your soil, but will need some time to break down in order to provide your plants it's benefits. It's also much cheaper to purchase.
If the Portland in your username is referring to Portland, Oregon I would highly recommend this local product. I use a lot of their soil amendments with great results.
Yes to Portland OR. Well shoot I just got this dang stuff. Maybe I’ll take your advice for next season and just use this sparingly on my flowers or something. Thanks for the advice! I’ll get some of that kelp meal for sure. I bet they’ll mark it down in the fall then I can add it and let it break down all winter. Are there any other supplements you recommend? Are you also in PNW?
